someone advice please

yo im growin some weed, my first time and they r doing well, almost flowering, but still in veg. and the seeds ii got were from some goodass weed. but idk what kind. is there anyway to tell if its sativa or indica? idk im way to new, someone help me out.

thanks

shorter, fatter leaves are indica (or indica dominant at least), skinnier longer leaves are sativa ( sativa dominant).
